A piston protection kit with tooling

Abstract

This invention discloses a piston protective sleeve assembly fixture, relating to the field of piston assembly technology. It includes a rotation mechanism comprising a rotatable stop seat on which a piston is mounted, and a protective sleeve fitted onto the piston; a flattening mechanism comprising a rolling plate with two symmetrically arranged arc-shaped pressure plates at one end near the piston; and a flattening wheel that contacts the side of the protective sleeve, pressing the top of the protective sleeve into the piston's annular groove. The flattening wheel contains a heating element. The rotation of the stop seat rolls the protective sleeve, ensuring the top of the sleeve is fully inserted into the piston's annular groove. The rolling plate's positioning prevents the top of the sleeve from detaching from the groove. Simultaneously, the heating element heats and shrinks the deformed protective sleeve, and the flattening wheel and auxiliary plate ensure the protective sleeve is completely fitted into the piston's annular groove.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of piston assembly, in particular to a piston protective sleeve assembly tool. BACKGROUND

[0002] As a key component in many mechanical devices such as engines and hydraulic cylinders, the working environment of the piston is often very harsh, and it has to withstand high temperature, high pressure, high speed friction and other harsh working conditions. In order to improve the performance and service life of the piston, it is necessary to treat its surface, such as electroplating, spraying wear-resistant layer, micro-arc oxidation and other processes. In these surface treatment processes, in order to avoid the influence of non-treatment parts or protect the treated surface from being damaged in subsequent processes, the piston surface treatment protective sleeve plays an important role. However, the installation of the protective sleeve is not easy, and many problems have been exposed in the past practice.

[0003] The traditional installation of the piston surface treatment protective sleeve relies on manual operation. However, manual operation has significant drawbacks. On the one hand, it is difficult to ensure the accuracy of the installation position of the protective sleeve; on the other hand, the efficiency of manual installation is extremely low, which undoubtedly increases the production cost and slows down the production progress in large-scale production scenarios.

[0004] Currently, there are some devices that can automatically install protective sleeves on pistons, such as Chinese patent application 201811034689.4, which discloses a method for installing a dust cover on a brake caliper piston. It has a rack and a feeding mechanism, an oiling mechanism, a pressing mechanism and a conveying line arranged on the rack. It can automatically complete the process of installing a dust cover on a caliper piston, and has high efficiency.

[0005] However, the protective sleeve used in the surface treatment process of the piston is reusable. Due to the nature of the protective sleeve, it is prone to deformation and expansion during long-term use, which affects the surface treatment of the piston.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0070] The present application provides a piston protection sleeve assembly tool as shown in Figures 1 to 9 The present application provides a piston protection sleeve assembly tool as shown in

[0071] The rotation mechanism 1 comprises a rotationally arranged stop seat 11, a piston 12 is arranged on the stop seat 11, and a protection sleeve is sleeved on the piston 12.

[0072] The flattening mechanism 2 comprises a flattening plate 21, two arc-shaped pressing plates 22 are symmetrically arranged on one end of the flattening plate 21 close to the piston 12, and the top end of the protection sleeve is limited.

[0073] The flattening wheel 23 is in contact with the side surface of the protection sleeve, and the top end of the protection sleeve is pressed into the annular groove of the piston 12, the heating element 24 is arranged in the flattening wheel 23, and the heating element 24 is an electric heating wire.

[0074] The flattening plate 21 is arranged on the piston 12, and the flattening plate 21 is in contact with the circumferential side surface of the piston 12.

[0075] Specifically, in use, the protection sleeve is sleeved on the piston 12, so that the top end of the protection sleeve is located in the annular groove on the lowermost side of the piston 12, then the flattening plate 21 is moved to approach the piston 12, and the flattening plate 21 is in contact with the circumferential side surface of the piston 12, then the flattening wheel 23 is moved to approach the piston 12, and the flattening wheel 23 is in contact with the circumferential side surface of the protection sleeve, then the piston 12 is rotated, the piston 12 drives the protection sleeve to rotate, the flattening wheel 23 applies radial pressure to the protection sleeve during the rotation of the protection sleeve, so that the top end of the protection sleeve completely enters the annular groove on the piston 12, and the flattening plate 21 limits the top end of the protection sleeve, further ensuring that the top end of the protection sleeve completely enters the annular groove.

[0076] When the protective sleeve is loosened due to continuous expansion deformation in a long-term cycle, the flattening wheel 23 is powered to the heating element 24 when it exerts radial pressure on the protective sleeve, so that the heating element 24 heats the flattening wheel 23, and the flattening wheel 23 directs heat to the protective sleeve, so that the protective sleeve shrinks under heat; it should be noted that the protective sleeve is made of silica gel material, which has the material property of shrinking under heat, and of course other materials with the property of shrinking under heat can also be used; at the same time, the flattening wheel 23 is moved to make the flattening wheel 23 closer to the protective sleeve, exerting greater pressure on the protective sleeve, and the flattening plate 21 is moved to make the flattening plate 21 closer to the protective sleeve, the pressing plate 22 at the end of the flattening plate 21 deforms under the action of pressure, and the flattening plate 21 drives the auxiliary plate 25 to move, so that the auxiliary plate 25 exerts greater pressure on the protective sleeve, and the protective sleeve after heating and pressing of the flattening wheel 23 is shaped.

[0077] By the arrangement of the flattening plate 21 and the flattening wheel 23, the protective sleeve can be rolled and pressed in cooperation with the rotation of the stop seat 11, so that the top end of the protective sleeve can completely enter the ring groove of the piston 12, and in cooperation with the limiting of the flattening plate 21, the top end of the protective sleeve is prevented from separating from the ring groove; at the same time, by the arrangement of the heating element 24, the deformed protective sleeve can be heated and shrunk, and in cooperation with the arrangement of the flattening wheel 23 and the auxiliary plate 25, the heated protective sleeve can be pressed and shaped, so that the protective sleeve is completely sleeved in the ring groove of the piston 12, and the subsequent surface treatment work of the piston is avoided.

[0078] As shown in Figure 4 , Figure 7 , Figure 8 The flattening mechanism 2 further comprises a moving part 26;

[0079] The moving part 26 comprises an electric cylinder 261, and the flattening plate 21 and the flattening wheel 23 are arranged on the output end of the electric cylinder 261, and the electric cylinder 261 drives the flattening plate 21 and the flattening wheel 23 to move;

[0080] The flattening plate 21 and the flattening wheel 23 are connected with the output end of the electric cylinder 261 through elastic members 262, and the elastic members 262 exert pressure on the flattening plate 21 and the flattening wheel 23;

[0081] The pressing plate 22 is located on the side of the flattening wheel 23 close to the piston 12.

[0082] Specifically, in use, when it is necessary to move the flattening plate 21 and the flattening wheel 23, the electric cylinder 261 is started, and the output end of the electric cylinder 261 drives the flattening plate 21 and the flattening wheel 23 to move. When the flattening plate 21 drives the pressing plate 22 to contact the piston 12, the flattening plate 21 slides to the rear side relative to the output end of the electric cylinder 261 under the blocking action of the piston, and the elastic member 262 is compressed, and the elastic member 262 exerts a pressure on the flattening plate 21 to move towards the piston 12. Then, the flattening wheel 23 contacts the protective sleeve, and the flattening wheel 23 slides to the rear side relative to the output end of the electric cylinder 261 under the blocking action of the piston, and the elastic member 262 is compressed, and the elastic member 262 exerts a pressure on the flattening wheel 23 to move towards the piston 12. The flattening wheel 23 and the pressing plate 22 assist the top end of the protective sleeve to enter the annular groove of the piston 12.

[0083] Through the arrangement of the moving piece 26, the flattening wheel 23 and the flattening plate 21 can be driven to move by starting the electric cylinder 261. Due to the position arrangement of the pressing plate 22 and the flattening wheel 23, the pressing plate 22 first contacts the piston 12 to limit the top end of the protective sleeve, and then the flattening wheel 23 exerts pressure on the protective sleeve, and cooperates with the elastic member 262 to continuously exert pressure on the protective sleeve.

[0095] Through the arrangement of the first slide rail group 264 and the second slide rail group 266, the flattening plate 21 and the flattening wheel 23 can move under the action of the electric cylinder 261 and can relatively move to adapt to the position change of the piston and the protective sleeve.
